Charmy grew up with a relatively normal childhood. He met the other Chaotix when on a family vacation on Carnival Island, and quickly became good friends despite the age difference. He really enjoyed helping people, and thus became very involved in the Chaotix Detective Agency. A couple years later, when Charmy's parents died in a car crash, Espio was more than happy to take Charmy in and take care of him.

Charmy is still somewhat a child, so he acts like one; he's hyperactive and has a huge imagination, which often distracts him from his work. The other Chaotix members find him annoying sometimes, but Charmy's happy-go-lucky nature usually helps the team stay positive. He's also one of the only people in the world who thinks Shadow is cool.

When writing this, I discovered that in the Archie comics, Charmy is supposed to be a prince. AND HE'S ENGAGED. ffffffThis is why I dislike the comics.
